This follows the pattern of what we’ve done with services, users and
events.
It gives us a way of neatly instantiating a model for each item in the
list we get back from the API and reduces the complexity of the view
layer code.
Now is a good time to do this because we’re going to be making a bunch
of changes to the jobs pages, and those changes will be easier to code
and understand with a sensible model behind them.
Now persisting the address to the "to" field of the Notification, after the notification has been validated.
If the letter is pending validation, then "Checking..." will appear as the identifier for the letter.
If the letter has passed validation, then the first line of the address (now persisted in the "to" field) will be displayed, with the client reference underneath.
If the letter has failed validation the "Provided as PDF" will show be displayed, which is now the initial value of the "to" field.
New units tests have not been written for this page because it is very like this will be refactor and probably a new template created for the page. Some design needs to go into this page.
But we needed something ready for user research.
Re-upload button is only shown if file failed validation.
Change wording of re-upload buttons
Make test we test right buttons on letter upload preview page
Also remove double backlink
The recipient of the letter now displays at the bottom of the page when
previewing a valid letter. The template preview `/precompiled/sanitise`
endpoint returns the address, but we format it to display on a single
line with commas between each line. We also need to convert the
recipient address to ASCII so that it can be stored as S3 metadata.
We mostly rely on the API returning a 404 to generate 404s for trying
to get things with non-UUID IDs. This is fine, except our tests often
mock these API calls. So it could look like everything is working fine,
except the thing your passing in might never be a valid UUID, and thus
would 404 in a non-test environment.
So this commit:
1. uses the `uuid` URL converter everywhere there’s something that looks
like an ID in a URL parameter
2. adds a test which automates checking for 1.
Decided it was better to call this then not. This does rely on
the file_id not being corrupted so the file_id passed
into `uploaded_letter_preview` is valid but am taking that risk
given it should only change if a user is changing the form html.
The overlay was showing for any invalid pdf - we only want to show the
overlay for invalid pdf files where there is content outside the
printable area.
We now use the pattern of showing a box at the top of the page with the
error. The error message has a heading and can have additional details.
Error messages and the invalid pages get stored in the S3 metadata.
We had been storing whether or not a file was valid in the S3 metadata,
but using the query string of the URL to store the original filename
and the page count. This meant that if you tried to view the preview
letter page without the query string you would see a `500`. It was
possible for this to happen if you were signed out of Notify while on
the preview page - you would be redirected back to the preview page but
without the query string, causing an error.
Added a send button which only appears on the page if the query string
indicates that the PDF is valid. Before actually sending, we check that
the service has the right permissions and that the metadata for the
letter confirms the letter is valid (because the query string can be
changed).
This sanitises uploaded letters and stores the sanitised result in S3
with if it passes validation or the original PDF in S3 if validation
fails. A metadata value of 'status' is set to either 'valid' or
'invalid'.
This checks that the PDF file is not malformed in some way (e.g. by
missing the EOF marker). We check this by trying to get the page count
of the letter which will be needed to display the preview of the letter.
Added a form to upload a single letter. Currently this only uses the
form to validate that a file is submitted and that the file is a PDF. If
either of these validations fail, the form will display an error.
Otherwise, we redirect to a new preview page which just has the filename
as the heading for now.
The uploads hub is just a page with text for now - there are no actions
available on the page. It is linked to from a new 'Uploads' menu item on
the left of the page which is only visible if your service has the
`letter` and `upload_letters` permissions and if the current user has
permissions to send messages.
